HAMMER.

Application filed January 12, 1924.' Serial No. 685,885.

My invention belongs to that general class of devices known as hammers, and relates particularly to aI hammer attachment or feeding device and controlling means therefor. More particularly it is a device fo-r use in connection with percussion hammers, bef ing especially suited lfor use on spring operated hammers in which the operator turns a crank or cranks when using the device to retract the spring. However, the device is ap plicable upon various other'types of hammers. v v v The inventionlias among itsv'objectsthe production of a device of the -kind described that is simple, convenient, compact, efcient and satisfactory for use Wherever found applicable. It has particularly as an object the production of al device that will hold the drill to the work and automatically feed the `same and cooperating means for controlling the same. I

Many other'objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosures 'herein given.

rIothis end my invention consists in the novel construction, arrangement and combination of parts herein shown and described,

claims.

In the drawings, wherein 'likereference characters indicate like or corresponding arts: p Fig. 1 is a side elevation of a hammer my improvement appliedthereto;

Fig. 2 is a sectional View taken substantially-on line 2-2 of lFig. 1;

Fig. 3 is a sectional view taken substantially on line 3,-3'-of`F ig. 1; and

Fig. 4t is asectional view taken substantially on line 4-1 of Fig. 1. l .Y Y

`Referring to the drawings, in which the spring type of hammer is' shown with ythe preferred form of my attachment applied thereto,1 represents the hammer barrel con; taining the usual spring and plunger or hammer head, and`2-2 the operatinghandles.V The hammer carries a chuck 3 vof Ysuitable form, in which is mounted a. tool 4tl ofthe desired size, shape and type.

I have shown the device in operative relation'with the work 5, which for purposes of explanation may be called a ceiling, yand 6 may be termed a. fioor. It may be mentioned,

however, that 5 represents the work to be is of some height particularly pointed out the holes iny ceilings, as it may be used to drill f in oors or'walls. In some cases, 6 .might represent a block, scaffold or other support, depending upon the height of the ceiling from` the floor. The present device is particularly adapted for use where the ceiling and where it may be necessary for the operator to stand on a step-ladder or the like in order to handleA the tool.

The extension consists of one or more telescoping parts 7 and 8 of the desired size,

shape and material, which normally may be freely extended or contracted to vary the length.

In the particular device shown, the f extension or feeding device is arranged for" attachment to the hammer l, the hammer being Vcomparatively short. This is generally preferred rather than to have part 8 as apart of the hammer. A simple connection is shown, consisting of the part 11 suitably( secured to the hammer, as for example by a bolt 12, and rwhich has a` part 13 connected as indicated at 14 and is adapted to be securedto part 8 either by threads thereon as` shown, or in an equivalent manner. Ar-

ranged on the part 8 `is a spring'l of .suitable tension, which is shown bearing at either end against the collars `17 and 20. The collar or sleeve 17 is in the form of a. clamp and is nor`V mally tightly secured in place by a bolt 19 and nut 18 or the equivalent. The clamping member 20 ordinarily is loose on the member 8, but may be vtightened to maintain the springconipressed, if desired, by means of" the bolt and wing nut21, similar' to the Wing nut 18and bolt 19 on the clamp 17. Mounted f lpart 7 by means of a'cable or rod 26 and clamping member 27 or equivalent means for the purpose.V Generally, I prefer to pro-videl a cable, rod or the equivalent 28 at the free 'end of arm28 so that the same may be operon they part 8 is a member 22 which'carries an v arm 23, the same being shown carried on the `fpm 24 and secured thereonby a; Cotter pin or ated from a distance when required. .The

collar 22 may be left loose on the member 8 or it may be tightened thereon, but generally lwhen the device is Vused on a hand-operated hammer, it is left loose so that as t-hezoper- V23 compresses the sprin;

ator gives the drill a short back and forth movement Whilev drilling, to. change the posltion of the cutting points or teeth of the drill, fthe arm will not interfere with him. For a power-driven hammer, the collar 22 is usually tightened so that the lever 23 'may be used to move the drill, as above described While drilling. Depressing end of the arm and contracts the extension, thereby with rawing the tool or drill from the hole. ,i

using the apparatus,.the tool 4 is set'at or about the point `wherethe hole-is` to be drilled, and the lower end ofthe extension set substantially directly below this point,

the tension ofthe spring on the device being.

controlled by means of the arm or lever 23.1

e Usually the moving and setting up is done fromgthe floor, the tool being setup with the drill against the ceiling about where the hole is to be drilled with the. bottom under to plumb and released so that thc spring pres--` sure `will hold the toolupright.-l 4The operator can then go` up the step-ladder, as drill- Vinnr is usually `done from a stepfladder, or

other support,and move the drillpoint to the exact position.` It is to be noted that at any time that the drill is removed fromthe hole for any purpose the device maybe released against the ceiling s0 that the entire tool will stand alone untilready to be moved to the next hole. Assuming that the tool is prop-v remove the tool or drill and insert the, exf pander and thence drive/the drill back into,A

the hole. Where it constitutes an expansion shell and remains there, 4 He can then `release the shell for drill from the chuck and by Ile-A pressing onthe lever23hmovcs the` tool dorwn so that it 4is free.

bearing against they collar 17 feeds thetool by applying pressure toithe hammer. (lbviously, this Apressure may bevvaried by shiftingor adjusting the collar` 17, or by length enifng partf. As collar QOis tifrhtened, all pressure of `theV spring'will be. l; collars 17 and 20A carried on part 7 soV thatthere will be no. tendency of the parts, 7 and I 8 to fly a i art at any time, and the spring will .be lockerV against loss if .parts 'Z and 8 are` etween the disassembled.

`lt shDlllClbe Plticularly noted that the. extension may be of any length, that is to4 say, live, terntw'enty, or even more feet, and part 7 may be made; 111.01m 01". more Sections suity `bylletters Patent is.: u It` may be particularly r noted that as he operatesthe tool, the spring ably secured together so that a large variety of lengths are obtained, making the tool apu plicab e for Work between different points 5 and, or a block or the like may be positioned under part Z 'for slight variations ofv height.

The 'one operator on'the ladder can Very conveniently'control the tool, both in drilling and inchanging by employingthe lever 2 3 or the operator :may confine himself to the operation of the hammer and interchang" u ing theftoolaeto., and the helperdown below controlfthe expansion `or contraction of the extension by means ofl the lever23 and cable 4 This ofimportance on Work of con` -siderable heiglianas the operator on the ladder;
